At Metrade, we offer high-quality spiral wound gaskets with inner rings designed for optimal sealing performance in water and industrial systems. Our gaskets are designed to provide long-lasting, leak-free sealing in high-pressure and high-temperature environments.

The inner ring in a spiral wound gasket is a key component that adds structural integrity and improves the sealing performance of the gasket. It is a metal ring that is placed inside the spiral wound gasket, typically positioned between the spiral wound layers and the flange’s sealing surface. While the spiral wound gasket itself consists of alternating metal and filler material layers, the inner ring provides additional support and ensures a more efficient seal.

The inner ring is commonly made of materials such as stainless steel, carbon steel, or alloy materials depending on the specific application requirements. The inner ring helps to prevent the gasket from expanding into the inner diameter of the flange, especially under high-pressure conditions. It acts as a barrier to keep the gasket tightly in place and reduces the risk of blowout.

By providing additional support, the inner ring prevents the gasket from deforming, especially under fluctuating pressures or thermal cycles. This makes it ideal for preventing leaks in systems where fluid containment is critical.
